-wmnow STRUCTURE.

To all whom z't may concern.' v l l3e it 'known thatv I, MAX N. KEELER, a c1t1zen'of. the "United States-'residing` at Urbana,in the county of Champaign and 5 State of Illinois, have invented certain new and useful Improvements in Window Structures, of which the following is a specification, reference being had therein to the accompanying drawing. A t

This invention relates broadly to window structures and more especially to window swinging andlocking devices.

The object of the invention is to provide simple and effective means that are readily and conveniently manipulated for swinging and locking a window without disturbing a screen which is also therein disposed.

Another object is to provide window swinging and fastening instrumentalities, of the type specified, which do not present an unsightly appearance.

Still another object within-the contemplation of my invention is to juxtapose the swinging instrumentality to the lockinginstrumentality so that they may be operated in conjunction, one with 'the other and whereby, when the window has been unlocked by the one instrumentality, it may be swung outwardly by the other. t

This invention in general seeks to provide a window-structure which is particularly adapted for use in window-easements wherein a screen is also mounted; and which structure from an operative standpoint will in cicncy and durability and which structurally considered will be of great simplicity.

There are other objects and advantages present in the invention, and these will 'be obvious from the accompanying drawings and the following description.

The invention resides broadly in the fea-` turcs of construction and in the novel cor- Specification of Letters Patent.

practical use possess a high degree of efliwithin the spirit thereof and within the objects contemplated thereby.

In these drawings;

Figure 1 is a view -in vfront elevation of a window-easement with my invention applied thereto;

lFig. 2 is a view in vertical section of the l same;

Fig. 3 is a view in horizontal transverse section on the line 3 3, Fig. 2; and' Fig. 4 is a fragmentary view in section of one portion of the structure.

In these drawings, the reference-numeral 1 designates the front or outer portion of a window-easement; 2 the rear or inner portion thereof; 3 the stool-portion, and 4: the top-piece.

Hinged or otherwise attached to the inner portion 2 of the Casement is a screen 5 of any suitable form and construction.

Hinged 'as at4 6, or otherwise attached, to the outer portion 1 of the easement is a window 7 of usual construction.

The stool-portion 3 is provided with a slot 8 in-which a window-actuating device has movement. This device comprises a swinging. arm 9 pivotally attached (as at 10) to the lower portion of the window, and a rack-arm 11 pivotally connected to the inner end of the arm 9'. The arm 9 is of a. length equal to the distance, approximately, between the pivot 10 and the plane of the front face 12 of the stool-portion. The arm Patented dpr.. 3, 19117.,

11 is of about the same length. Hence,

when the window is closed, as shown in Figs. 1 and 3, for instance, the arm 11 will lie parallel to the front face of the stool-portion while the arm 9 will occupy a position substantially at right-angles thereto, and, thus-beneath the overhanging-ledge of the stoo Secured to the stool-portion and in alinement lwith the slot 8 is a rack-engaging plate 13 with which a series of teeth 14on the rack-arm 11 are engageable. Thereby, the window-actuating device may be heldl Vagainst; movementand, thus, the window is rigidly held against closing. When th'e rack-arm 11 is in the aforementioned angular position shown in Figs. 1 and 3, the window is securely held against opening.

To supplement this holding action of the window-operating device, I' may provide a window-locking device. In this instance, this device is shown as including a vertical i spindle'148L journaled at 15 and 16 in the Casement. It carries a series of hooks or angular projections 17 that are adapted to engage a corresponding series of eyes 18 on the window-sash.

Means are provided for rotating the spindle, and these comprise a pinion 19 fast on the lower end of the spindle and meshing with a corresponding pinion 20 on the outer end of a stub-shaft 21 journaled in the casement. Tlis, in turn, carries a crank 22 on its inner en Operation: Assuming that the window is closed, as shown in full lines in Fig. 3, and itV be desired to open it, the operator turns the crank 22. This rotates the shaft 21 and, through the pinions 19 and 20, the spindle 14a. In this way, the hooks are withdrawn from the window-eyes. Thus, the window is free to be opened. This opening is accom-v plished by swinging the rack-arm so that it will occupy the position shown in dotted lines in Fig. 3. The operator then pushes on the rack-arm and this causes the swinging arm to swing the window outwardly on its hinge. The rack-arm may then engage the plate 13, as shown in Fig. 4, and this will lock the window in its opened position.

If, now, it be desired to close the window, the operator disengages the rack-arm from the plate by lifting the former slightly and, then, pulls the actuating device inwardly. When the window hasthus been closed, the rack-arm is swung back to its angular position and serves to lockthe window. The crank may then be manipulated 'to effect an engagement of its hooks with the windoweyes sothat the window is,'thereby, additionally locked.

As will be seen, these operations of swinging the window and locking and unlocking it may be accomplishedwithoutzdisturbing the screen 5.

It is within the contemplation of my invention to utilize the disclosed structure for ypositioning* and locking swinging instrumentalities, other than windows.

From the foregoing, it will be perceived that I have succeeded in devisin a windowoperating structure which is wel adapted to achieve the objects and ends in view.

It is to be understood that the particular embodiment herein shownand described is exemplary and that all matter contained in the foregoing description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim is:

A window structure comprising a casement provided with a triangular recess, disposed with a base thereofforming an enlarged opening on the outer side of the casement, and the apex thereof forming a restricted opening upon the inner surface of the easement; a window hinged in proximity to the enlarged opening formed by said recess; and a window locking and actuating device comprising a swinging arm pivotally connected to said window at a point removed from its hinged connection to the casement; said arm being of a length approximately equal to the width of the casement and normally occupying a position Within the recess; al portion of the free end of said arm protruding beyond the inner surface of the easement when the window is in closed position; a rack arm having at one endpa handle, and pivotally connected at its "opposite end to the swmgmg arm; said rack arm normally occupying a position outside the restricted opening formed by said recess on the inner side of the easement, and in approximate alinement with said inner side for locking the window in its closed position; and a rack plate s ecured to the casement at an edge of the restricted opening in the triangular recess, and adapted to be engaged by the rack arm when the latter occupies a position within the triangular recess to hold the window in a plurality of positions; said swingingarm having a longitudinal movement at its free end, in the triangular recess, approximately equal to the widest portionV of said recess, said swinging beingeffected upon its point of .connection with the rack arm as a pivot, when the rack arm is actuated to. open the window.

In testimony whereofI aiix my signature in presence of two witnesses.
